The advancement of large language models (LLMs) has significantly broadened the scope of applications in natural language processing, with multi-modal LLMs extending these capabilities to integrate and interpret visual data. However, existing benchmarks for visual language models (VLMs) predominantly focus on single-image inputs, neglecting the crucial aspect of multi-image understanding. In this paper, we introduce a Multi-Image Relational Benchmark MIRB, designed to evaluate VLMs' ability to compare, analyze, and reason across multiple images. Our benchmark encompasses four categories: perception, visual world knowledge, reasoning, and multi-hop reasoning. Through a comprehensive evaluation of a wide range of open-source and closed-source models, we demonstrate that while open-source VLMs were shown to approach the performance of GPT-4V in single-image tasks, a significant performance gap remains in multi-image reasoning tasks. Our findings also reveal that even the state-of-the-art GPT-4V model struggles with our benchmark, underscoring the need for further research and development in this area. We believe our contribution of MIRB could serve as a testbed for developing the next-generation multi-modal models.

• [2024/07] We have integrated MIRB into lmms-eval. You can also evaluate your model on our benchmark from there.

conda create -n MIRB python==3.10 -y
conda activate MIRB
pip install -r requirements.txt
# optional
# pip install flash-attn --no-build-isolation --no-cache-dir

You should be able to run most of the models now, but may also want to check some models for specific requirements such as LLaVA, VILA, and Qwen-VL.

Put huggingface data in ./MIR and unzip ./MIR/images.zip.
